To all whom it may concern: 7

Be it known that I, EDWARD J. BROGAN, a citizen of the United States,residing at Yonkers, in the county of Westchester and State of New York,have invented new and useful Improvements in Photographic- PrintingFrames, of which the following is a s ecification.

ob'ect of the invention isto provide a frame or use in makingphotographic prints.

The invention embodies, among other features, a device wherein a tracingor picture, from which it is desired to make a print, is fed into acasing to lie in an exposed position immediately in front of asensitized paper, the impression of the original picture being thentransferred on to the sensitized pa or by the action of the sun or otherlight, after which the sensitized aper, together with the picture, isremove from the casing and the sensitized paper is then subjected tovarious chemical treatments in order to reproduce a copy of the originalpicture.

My device is particularly adaptable for use in making blue prints by theaction of the light of the sun and for this reason the device ispreferably mounted in a window with a portion of the device projectingoutwardly therefrom and having a face thereof exposed to the sun so thata clear and effective blue print can be readily and quickly produced.

In the further disclosure of the invention reference is to be had to theaccompanying drawings constituting a part of this specification, inwhich similar characters of reference denote corresponding parts in allthe views, and in which:

Figure 1 is a vertical sectional view of a window casing showing mydevice mounted therein, the device being shown in elevation;

ig. 2 is a similar View, the device being shown in vertical section;Fig. 3 is a horizontal sectional view taken on the line 33 in Fig. 1;Fig. 4 is a vertical transverse sectional view taken on the line 4;4= inFig. 1; and Fig. 5 is a transverse sectional view taken on the line5-5in Fig. 1.

Referring more particularly to the views, I disclose a window casing 10having the usual sill 11 and sash 12, a casing 13 being mounted torepose upon the sill 11 and having secured to the front end thereof adownwardly extending auxiliary casing 14, the

forward end of the casing 13 being projected beyond the sill in orderthat the auxiliary casin 14 can be arranged to extend downward y at anangle to the casin 13, the lower part of the sash 12 being adapted toengage the upper face of the casing 13 to secure the casing 13 on thesill ll, an suitable locking member 15 being re erably employed forengagement with t e sash 12 to retain the same in rigid position andlock the casing 13 on the sill 11.

The rear end of the casing 13 projects inwardly beyond the sill 11 andmounted to swing thereon is a closure 16, a slotted supporting member 17being secured to the closure 16 and having arranged to operate in theslot thereof a suitable pin 18 secured to a side of the casing 13, theslot in the supporting member 17 being of sufficient length so that whenthe closure 16 is in open position the same will lie in the horizontalplane of the lower side or bottom of the casing 13, whereas when theclosure is moved into closed position, the mentioned closure will closethe rear end of the casing, as shown, a suitable catch 19 being providedon the closure 16 and adapted for engagement with the casing 13 toretain the closure in closed and locked position.

' A plurality of uprights 20 are secured to the closure 16 and extendlaterally thereto and journaled on the uprights and between the same isa roller 21 adapted to contain a roll of sensitized paper 22. Apartition 23 is preferably provided in the rear end of the casing 13 toform a compartment 24 adapted to receive the roller 21 and roll ofsensitized paper 22 when the closure 16 is moved into closed position,the mentioned compartment being light-tight so that the sensitized paperwill not be subjected to the light when the device is not in use, ahorizontally arranged slot 25 being provided in the partition 23 andthrough which the sensitized paper and the original picture from whichit is desired to obtain a print, are passed when it is desired toproduce a print on the sensitized paper.

Bearings 26 are mounted to slide in slots 27, formed in the side wallsof the casing 13 and journaled on the said bearings are coacting rollers28, 28*, one of said rollers being arranged above the other in orderthat the sensitized paper can be fed therebetween, suitable headedtension members 29 being journaled in the side walls of the casing 13and having threaded connection with the bearings 26 in order that thebearings can be advanced or retreated in the slots 27 when the saidtension members are rotated relatively to the casing 13.

Suitable rollers 30, and 30 are journaled in the front end of the casing13 and journaled in the lower part of the auxiliary casing 14 arerollers 31, 31, an endless trans parent apron 32 being arranged withinthe casing 13 and auxiliary casing 14 to pass around the rollers 28, 30,31*, 31 and 30,- the rollers 30, 31 and 30 being adapted to act as guiderollers for the apron while the roller 31 constitutes one of the endrollers at the lower end of the auxiliary casing 11 and the roller 28constitutes the other end roller in the rear end of the casing 13. Inasimilar manner, an endless oqaque apron 33 is mounted to pass over therollers 28", 30, 31 and 30", the roller 31 constituting an end roller atthe lower end of the auxiliary casing 14 and the roller 28 constitutingan end roller at the rear end of the casing 13, while the rollers 30 and30 act as guide rollers for the opaque apron 33, the mentioned rollers30 and 31 being also adapted to act as guide rollers for the transparentapron 32 as mentioned heretofore, and as will be readily seen byreferring to Fig. 2. It will now be seen that by operating the tensionmembers 29 to actuate the bearings 26 in the slots 27, the tension ofthe aprons 32 and 33 can be readily adjusted.

A shaft 34 is extended from one end of the roller 28*, said shaft alsoconstituting the means whereby the roller is journaled on one of thebearings thereof and the said shaft being adapted to project beyond aside of the casing 13 and havin keyed thereto a toothed drum 35, asuitab e handle 36 being also keyed to the free end of the shaft 34 forthe purpose of imparting rotation to the drum 35, thus also rotating thecoacting rollers 28 and 28*. A bracket 37 is secured to the bearinghaving the shaft 34 journaled therein and the said bracket extendsoutwardly over the drum 35, the mentioned bracket being bifurcated toform a track 38 on which is mounted to slide a grooved wheel 39 having apin 40 depending therefrom and operable in the grooves formed betweenthe teeth of the drum 35, it being readily understood that the groovesin the mentioned drum 35 are cut sufiiciently deep in the drum so thatwhen the drum is rotated, thus advancing the grooved wheel 39 over thetrack 38, the drum will be locked in rigid position and prevented frombeing turned at the moment the pin 40 reaches the extremity of thegroove in the drum, it bein understood that the groove is of acontlnuous nature, as formed by the teeth on the drum,

In the use of the device described, an end of the sensitized paper 22 ispassed through the slot 25 in the partition 23 and between the coactingrollers 28* and 28*, after which the tracing is also fed between, therollers 28, 28 and then by means of the handle 36, rotation is impartedto the drum 35, thus resulting in the rotation of the rollers 28, 28*and impartin rotation to the aprons 32, 33, the sensitize paper andtracing being received between the aprons so that the sensitized paperand tracing will be simultaneously advanced into the auxiliary casing14, the front face of the auxiliary casing being open in order that thetracing and sensitized paper will be readily exposed to the light of thesun. The length of the groove on the drum 35 is made in properproportion to the length of the casing 13 and auxiliary casing 14 sothat at the moment the pin 40 of the carriage 39 reaches the end of thegroove, thus locking the drum against rotation, the tracing and portionof the sensitized paper beneath the tracing will lie in the open part ofthe auxiliary casing 14. The tracing and sensitized paper are nowexposed to the light of the sun for a time suflicient to produce animpression upon the sensitized paper, said impression being a duplicateof the picture on the tracing, and the handle 36 is then rotated in theopposite direction to reverse the former rotation of the drum and alsoreverse the former rotation of the rollers 28"-, 28 thus retreating thetracing and sensitized paper from the auxiliary casing 14 into thecasing 13 vand thence outwardly through the slot 25 in the partition 23,after which the rotation of the handle 36 is again reversed to receive anew portion of the sensitized paper and another tracing.

The transparent apron 32 can be conveniently made of celluloid or otherflexible transparent material and the apron 33 is preferably made ofcanvas in order to present a roughened surface that will grip thesensitized paper to simultaneously advance the sensitized paper andtracing in the casing 13 and auxiliary casing '14, the drum 35 and pin40, operating in the continuous groove of the drum, being adapted tolimit the advancement of the sensitized paper and tracing in theauxiliary casing 14, as mentioned heretofore.

By providing a device of the character described, the process ofphotographic printing can be efliciently and expeditiously carried onand by having the sensitized paper and tracing arranged to lie betweenthe transparent apron 32 and opaque apron 33, the mentioned tracing andsensitized paper will at all times lie flat and smooth, the tension ofthe aprons 32 and 33 being adapted to retain the tracing and sensitizedpaper in close relation so that an accurate and clear print can beobtained upon the sensitized paper.

It should be noted that by arranging the casing 13 and auxiliary casing14 in the manner described heretofore, the device disclosed will take upfar less room than the devices now generally used and which are usually0 erated over a track extending from within a building to the exteriorthereof, and it will be further noted that my device can be readily andquickly removed from the window casing 10 when it is not desired to usethe same.

Having thus described my invention, I claim:

1. In a device of the class described, the combination with a casing, ofan auxiliary casing projecting from the front end of the said casing, aclosure for the said casing, a roller journaled on the said closure andadapted to contain a printing material, rollers journaled in the saidcasing and said auxiliary casing, a continuous transparent apron mountedto operate over a plurality of the said rollers, a continuous opaqueapron mounted to operate over aplurality of the said rollers, and meansfor actuating the said aprons and feeding the said sensitized materialtherebetween.
